Modular insulated container system

ABSTRACT

A modular container for consumable products includes a first receptacle, defining a first volume, and a second receptacle, defining a second receptacle volume. Joining means for joining the first container and the second container has first and second sides and is adapted for positioning between the containers at the open ends. The joining means covers the open end of the second receptacle when placed in engagement with the second receptacle open end to form a sealed joint in a joining means combination. The joining means combination has a first attachment mechanism for removably attaching the combination to the open end of the first receptacle such that the joining member is interposed between the first and second receptacles.

FIELD OF THE INVENTION

Generally, the invention includes insulated vessel technology, more specifically, sectional insulated vessels.

BACKGROUND OF THE INVENTION

The origin of bento can be traced back to the late Kamakura Period (1185 to 1333), when cooked and dried rice called hoshi-ii (literally “dried meal”) was developed. Hoshi-ii can be eaten as is or boiled with water to make cooked rice, and is stored in a small bag. In the Azuchi-Momoyama Period (1568 to 1600), wooden lacquered boxes like those of today were produced and bento would be eaten during a hanami or a tea party.

In the Taishō period (1912 to 1926), the aluminum bento box became popular as a luxury item because of its ease of cleaning and its silver-like appearance. Bento regained its popularity in the 1980s, with the help of the microwave oven and the proliferation of convenience stores. While, in convenience stores and at train station vendors, the expensive wood and metal boxes have been replaced with inexpensive, disposable polystyrene boxes, handmade bento in elaborate steel boxes have made a comeback. Bento boxes are still used by workers as a packed lunch, by families on day trips, for school picnics and sports days etc.

In the tradition of the bento, there have flourished a number of insulated container devices for consumable products, such as thermos bottles and lunch boxes. Food containers with multiple compartments also exist. One trend in lunch boxes is represented by the lunch sack generally made of vinyl, with foam insulation, and an aluminum sputtered on vinyl interior. As a result, such lunch sacks usually much better than traditional bento at retaining their temperature but are less rigid and, thus, much less protective of the enclosed food. A distinct development has been the steel lunch box having rigid insulated walls that preserve the temperature of the food they contain.

Efforts at placing the varied content of a lunch within a multiply chambered insulated vessel include U.S. Pat. No. 5,366,089 to Parker for a Separable Food and Beverage Container Combination. Parker describes one example of a separable container combination for food and beverages, but requires a large number of parts and does not provide for separation means between open ends of two containers in the container combination. Instead, the combination has the opposed end of one container adjoining the open end of the other container when the combination is attached together, thus requiring a separate cover piece for the second container.

Another such effort is taught in U.S. Pat. No. 4,474,303 to Maccise for a Portable Modular Food Container. Maccise, like the U.S. Pat. No. 5,366,089 patent to Parker, requires a large number of parts and does not provide separation means between the open ends of the modular containers described in the patent.

U.S. Pat. No. 4,496,068 to Blease demonstrates a Container Assembly which has only three main parts to form two separable containers, but, as in the devices disclosed in the above discussed patents, the opposed end of one container abuts the open end of the other container when the two containers are attached together. A cover for the second container is also exposed, making it easy to inadvertently loosen or remove. The cover for the second container is small in relation to the container itself, which makes the container difficult to clean and impedes access to the contents of the container if they are not a liquid with low viscosity.

Therefore, a need exists for a multiply sectioned container system for enclosing consumable products wherein the system does not require a separate lid for each formed section. A further need exists for a sectioned container for consumable products adapted to receive products having differing volumes.

SUMMARY OF THE INVENTION

By providing a modular container system for consumable products having at least first receptacle defining a first volume with an open end and a opposed end, a second receptacle defining a second volume with an open end and a opposed end, and a septum adapted for positioning between the receptacles at the open ends for separating contents of the first receptacle and the second receptacle. In a presently preferred embodiment, elements also known as modules of the modular system are formed of double-walled stainless steel wherein the volume between the double-walls has been evacuated to enhance insulating properties of the double-walled module. An alternative embodiment substitutes a polymeric material for the stainless steel to capitalize on the polymeric material's inherent properties allowing for ease of manufacturing and cleaning The a presently preferred embodiment includes rubberized grip surfaces on the exterior of the first and second receptacles, and cooperative series of threads so that the septum may be securely and removably attached to the second receptacle and the second receptacle and septum combination may be removably attached to the first receptacle. A presently preferred embodiment employs bayonet mounts rather than threads for positive engagement and to prevent cross-threading in use. The at the threads or bayonet mounts, modules may also include one or more annular fluid seals to prevent any fluid or partially fluid contents of the containers from leaking and to better maintain the freshness of non-fluid contents.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 is a situational view of two embodiments of a modular insulated container system shown as used in a casual picnic at the Crissy Field Picnic Area. Portrayed in the tableau, a couple uses a first inventive embodiment generally 10 and a second inventive embodiment, generally 20. The first embodiment 10 includes Dewar flask 11 having a septum base 13 and a utensil bin 12. A tumbler 15 rests alongside the Dewar flask 11 and might alternatively be engaged atop the Dewar flask 11 when the first embodiment is transported, such as to a car in a parking lot. Cheese and crackers rest on a septum platter 22 alternatively used to top the second embodiment 20 when transported. Cups 17 with which the couple toasts the weather and utensils 19 resting on and alongside the septum platter 22 will nestingly store within the utensil bin 12 during transportation.

The portrayed first and second embodiments 10, 20 are further advantaged by the wheeled caddy (not shown) that receives each of the embodiments on mounting pads affixed to a spine running between the spaced apart wheels and a handle. The mounting pads on the wheeled caddy engage the first and second embodiments in one of either of screwing or bayonet-style engagement for secure transportation with additional holding restraint during movement. The wheeled transport will foldingly stow in small spaces upon removal of the embodiments of the invention. Alternate embodiments of the wheeled cart may, optionally, include more than one pad for one or the other or both of the embodiments. Thus, the couple easily transported the embodiments across the parking lot and over the sand from the notoriously small boot in his vintage 1971 Jaguar XKE Series 3 V-12 to the beach where the couple is here portrayed.

Referring, now, to FIG. 2, a study of a cross-sectional view of the first embodiment 10 reveals Dewar flask 11, with a stopper 33 and septum 13 resting in screwing engagement with the utensil bin by joining a tube member 17 in screwing engagement to a base 31. With these basic building blocks, the modular design of the invention is revealed.

Modular design, or “modularity in design” is an approach that subdivides a system into smaller parts (modules) that can be independently created and then used in different systems to drive multiple functionalities. A modular system includes functional partitioning into discrete scalable, reusable modules consisting of isolated, self-contained functional elements with Rigorous use of well-defined modular interfaces.

Besides reduction in cost (due to lesser customization, and less learning time), and flexibility in design, modularity offers other benefits such as augmentation (adding new solution by merely plugging in a new module), and exclusion. Modular design seeks to combine the advantages of standardization (high volume normally equals low manufacturing costs) with those of customization.

A modular insulated container system, in accordance with the principles of the invention, then, is generally indicated at reference numeral 10. In explanation of the modular nature of the invention, the key concept to grasp is that

In each configuring any of the embodiments, there is one instance of joining one element to another. Referring to FIGS. 3, 4, and 5, one of the strengths of the modular design of all of the embodiments is demonstrated to be in the flexibility the design enables. A stopper 33 and the Dewar flask 11 cooperate to define a first receptacle 42 which has a first receptacle open end 44 and a first receptacle opposed end 46 defining a first volume 48. The tube member 17 cooperating with the base 31 forms a second receptacle 52 which has a second receptacle open end 54 and a second receptacle opposed end 56 defining a second volume 58. The septum 13 with a first side 131 and a second side 132 is used to separate the first receptacle 42 from the second receptacle 52 and is interposed between the first receptacle open end 44 and the second receptacle open end 54.

In selecting the septum 13 to join the first receptacle 42 to the second receptacle 52, the user has elected to form two distinct volumes, the first receptacle volume 48 and the second receptacle volume 58. The insulated septum 13 having its first side 131 engages the first receptacle 42 at its first receptacle open end 44, thereby completing the enclosure of the first receptacle volume 48 rendering it capable of insulatedly storing a food or beverage. The insulated septum 13 can, as is illustrated in FIG. 2, engage at the septum second side 132, the tube member 17 cooperating with the base 31 to form the second receptacle volume 58. Upon screwing engagement with the septum second side 132 at the second receptacle open end 54, the tube member 17 insulatedly encloses the second receptacle volume 58. As such it, too, can insulatedly store a food or beverage just as the first receptacle volume 48 can store a food or beverage without fear of changing the temperature of either food or beverage or of mixing them.

As is shown in FIG. 3, access to the second receptacle volume is readily achieved by the disengaging of the septum second side 132 from the second receptacle open end 54. While illustrated in drawings as a threaded engagement, the presently preferred engagement is a bayonet mount. Either, however, will well serve the object of the invention. Wherever within this application, the verb or adjective “screwing” is used, it is the intent of the applicant to encompass, alternatively, “engaging a bayonet mount” as the context might indicate.

A bayonet mount or bayonet connector is a fastening mechanism consisting of a male probe with one or more pins, and a female receptor with matching L slots and spring or springs to keep the two parts locked together. To couple the male probe with the female receptor, the pin or pins on the male probe are aligned with the slot or slots on the female receptor and the two pushed together. Once the pins reach the bottom of the slot, the two receptor and probe are turned in opposite directions to guide the pin across the bottom of the L shaped slot. The spring or springs then hold the pin in position to prevent it from backing out. To disconnect, the probe and receptor are pushed together to overcome the spring whilst twisting slightly to reverse the locking turn.

The strength of the joint relies on the shear strength of the pins and the strength of the L slots which hold the pins in place when locked. A practiced user can connect them quickly and they are not subject to cross-threading. For this reason, in the presently preferred embodiment, the septum second side 132 can be manually removed from the second receptacle open end 54 by a user's thumb and index finger.

FIG. 3 shows the second receptacle 52 removed from the first receptacle 42 and resting on a flat surface with the second receptacle open end 54 facing up for easy access to food or beverages such as salad dressing which may be contained therein. As illustrated in FIG. 1, the formed utensil bin 12 may be used to stow the individual utensils 19 and cups 17 for the picnic, so the utility of the modular system is not strictly limited to food alone.

By selective use of modular components, the system enables two distinct relationships between the first receptacle volume 44 to the second receptacle volume 54 as that relationship is defined by either of the intervening septum 13 or the connector 23. When used with the connector, the first receptacle volume 44 is conjoined with the second receptacle volume 54. In still another configuration, the first receptacle volume may simply be enclosed by engagement between the first receptacle 42 and the base 31.

Shown as well in FIG. 4 is the connector 23 which in appearance and in use is very similar to that of the septum 13 in that the connector 23, at its first side 231, also engages the first receptacle 42 at its first receptacle open end 44, but is distinct as the connector 23 does not complete the enclosure of the first receptacle volume 48. To render the first receptacle 42 capable of insulatedly storing a food or beverage, the second receptacle 52, at its second receptacle open end, engages the connector 23, at its second connector side 232 to the second receptacle volume 58. Upon such engagement, a connector communicating volume 238, provides an interstitial volume to communicate between the first receptacle volume 44 and the second receptacle volume. As such, the so-configured modular system 10 can perform as any double-walled bottle such as those sold under the Thermos™ Stainless King Beverage Bottle™ or the Stanley™ Classic Stainless Steel Vacuum Bottle.

FIGS. 5 and 6 demonstrate the flexibility of the system. Consider a user's desire to bring diverse foods such as chili and pudding to school for lunch. As the foods that user selected must both be insulated from the ambient and from each other, they must be contained in distinct volumes. To that end solutions such as the Zojirushi™ Mr. Bento Stainless Steel Lunch Jar™, a single double-walled wide-mouthed stainless steel vacuum jar enclosing individual polymeric containers will not meet the user's need. The configuration of the modular system 10 shown in FIGS. 5 and 6, will, however.

On again, the so-configured system 10 defines the first receptacle 42 using a first tube member 17 connected to the septum 13 and enclosed at the first receptacle opposed end 46 by threaded engagement with a lid 32. The first receptacle 42 enclosates the first receptacle volume 48 generally contained in the first tube member 17. The elements of the lid 32, the first tube member 17 and the septum 13 cooperate to form the first receptacle and when form serve to keep the temperature within the first receptacle volume 48 at a constant level to maintain the freshness and crispness of the exemplary food item, pudding with fruit inclusions.

A second receptacle 52 is defined, in cooperation with the septum 13, by the second tube member 17 in engagement with the base 31. Just as the first tube member 17 encompasses the first receptacle volume 42, the second tube member 17 encompasses the second receptacle volume 52 and, likewise, keeps that volume 52 insulated from the ambient and from the first receptacle volume 42. Thus, in the example, the piping hot chili, the second receptacle volume 52, remains piping hot without heating the pudding within the first receptacle volume 42.

FIG. 6 shows the first receptacle 42 and the second receptacle 52, each open to the ambient for access. As is evident from comparison of FIGS. 5 and 6, access to the first receptacle volume 48 is achieved by separation of the first tube member 17 from the lid 31, while access to the second receptacle volume 58 is achieved by separating the second tube member 17 from the septum 13, while the septum 13 remains engaged to the first tube member 17 to contain the first receptacle volume 48.

Continuing then, to FIGS. 7 and 8, As is evident in the foregoing explanation, the modular system in every embodiment includes at least one of a tube member 17 or Dewar flask 11 with either of threaded or bayonet mount engagement with one of a stopper 33, a lid 32, a septum 13, or a connector 12. As must also be evident, nothing limits the embodiment to a first receptacle 42 joining a second receptacle 52. Indeed, the septum 13 could further join another tube member 17 and a base 31 forming a third receptacle 62 enclosing a third receptacle volume 68 and likewise stack still further receptacles to contain such a diversity of foods, beverages, or utensils, as a user might need. As illustrated, utensils 19 might be contained in one of the receptacle volumes such as in the second receptacle volume 58. A beverage might reside in the first receptacle volume 48, advantageously defined by a Dewar flask 11 rather than a tube member 17, and hot food is contained in the third receptacle volume 68, the third receptacle 62 defines.

FIG. 9 portrays a variation on the embodiment shown in FIG. 7. Rather than to use the septum 13 that provides a bottom to contain the first receptacle volume 48, a second septum 13 is used. Thus, distinct septae 13 are used allowing the first receptacle 42 to separate from the second receptacle 62 without exposing either of the first receptacle volume 48 or the second receptacle volume 68 to the ambient. Such a user-selected configuration prevents the introduction of contaminants, such as sand at a beach, when the first receptacle is set down on, for example, a beach blanket. Thus, where the septum 13 attached to the first receptacle 42 serves as a base, the septum 13 does not draw sand into the second receptacle 62 when the receptacles are rejoined. Ring members 17 d and 17 g in FIGS. 14 and 15, infra, also serve the same function of allowing two septae 13 a, 13 b to join, protecting the contents of the second receptacle 62.

A strength of the modular system is its ability to meet the needs of the user. When used with the wheeled cart described above, a plurality of modules could bring a feast of divergent foods to a location with a minimum of effort.

The further exploitation of modular elements in various configurations meets a variety of user needs. For example, in FIGS. 10 and 11, to shelter and insulate a glass wine bottle 91 and two glass wineglasses 92, tube members 17 are configured with other elements to form transportable cases. For the wine bottle 91, two tube members 17 are joined by engagement to the connector as earlier described. The lid 32 and the base 31 join to form an outer shell 33 a. Addition of a first compressible formed liner 34 a (by way of nonlimiting example, a neoprene liner), and a second compressible formed liner 34 b complete the case.

Modifying the first outer shell 33 a by substituting the septum 13 for the connector 23 forms the second outer shell 33 b. Placing a third formed liner 33 c in each of the resulting enclosed volumes, the case is suitable for transportation of the wineglasses 92 with minimal risk of breakage.

While the diameter of the foregoing examples has been suggestive of single embodiment of roughly the same dimensions as the Thermos™ Stainless King Beverage Bottle™ or the Stanley™ Classic Stainless Steel Vacuum Bottle, nothing in the nature of the invention limits the diameter. By way of demonstration, FIGS. 12 and 13 show a 12″ embodiment of the modular system showing the system's ability to mimic the functionality of a pie safe, a cooler, and a spigoted jug.

As noted several places in the discourse above, the engagement between the tube member 17 and the several modular elements is shown to be threaded engagement for ease of illustration and understanding but in the presently preferred embodiment bayonet mount engagement achieves the structurally rigid sealing union between the tube member 17 and the sundry elements. While not shown, the sealing union in a presently preferred embodiment includes a conventional, food grade O-ring seated on a peripheral rim on each modular element as appropriate to assure a liquid tight seal.

FIGS. 12 and 13 show two configurations of an embodiment having a 12 inch diameter. As stated above, the versatility of the modular system 20 and the range of suitable dimensions allow the use, as shown in FIG. 11, of a first receptacle volume 48 a defined, in part by the lid 32 a and the septum platter 22 as a pie safe. A second receptacle space 58 a defined in part by the two portrayed septum platters 22 serves as a cooler containing, for example, canned beverages 95, wrapped product such as cheese 94, and polymeric containers 96 such as those by Tupperware™, and all are cooled by the presence of ice 99. In a third receptacle space, partially defined by the second septum platter 22 and the base 31 a, a slightly modified tube member 17 b includes a spigot 88 allowing the space to contain a liquid beverage such as lemonade 97 cooled, again, by the presence of ice 99.

Comparing FIGS. 12 and 13, the modular system, again, shows its versatility. In substituting a connector member 23 a, the user allows a greater volume of the lemonade (in this nonlimiting example) to fill both of the second receptacle space 58 a and the third receptacle space 68 a as those spaces are joined by the communication the connector 23 a enables. The first receptacle space 48 a now serves as the cooler that had, in FIG. 11, occupied the second receptacle space 58 a.

While the foregoing discussion sets forth the presently preferred embodiment, the threading scheme as to which elements will bear a “male” or a “female” configuration. In electrical and mechanical trades and manufacturing, each half of a pair of mating connectors or fasteners is conventionally assigned the designation male or female. The “female” connector is generally a receptacle that receives and holds the “male” connector. Referring then, to FIGS. 14 and 15, in the foregoing discussion, the lid 32 a has been suggested to have a female threading at its open end. In FIG. 14, however, the lid 32 is shown in an equally facile embodiment with the threading on the outside of the peripheral rim rather than the inside as in the lid 32 a (FIG. 13). As might be evident in this discussion, the nature of the various embodiments is determined, generally, by the threading combinations (remembering that “threading” is defined herein as including, as well, bayonet mounting, a manner of engagement to which the “male” and “female” descriptors apply with equal vigor.) that occur on the tube member 17 generally. In the preceding description, the tube member 17 has been described in its preferred embodiment having both a male and a female engagement at opposed ends of the tubular member 17 generally.

FIG. 14 portrays a tube member 17 c with two male thread sets on opposed ends. Selection of male threads on the tube member drives the selection of female threads on each of the possible engaging surfaces on any of the joining members, a group comprising such as the lid 32 a, the connector 23 a, the septum 13 a, and the base 31 a. Likewise, the Dewar flask (not shown) must share the same threading pattern as the tube member 17 c, in order to engage each of the joining members, the lid 32 a, the connector 23 a, the septum 13 a, and the base 31 a. In such a manner, the alternate embodiment performs with equal facility as the preferred embodiment. To further accommodate the use of this embodiment, a shortened tube member 17 c called a ring member 17 d is used as a “gender changer” allowing septae 13 a to be joined to create distinct first and second receptacles.

Also notable is the variant on the lid 32 a as characteristic of the nature of the disclosure the specification comprises. While the discussion has focused upon the engagement between modular elements, variants of each of the elements are possible, such as the addition of a handle 82 to the lid 32 a while remaining entirely within the spirit of the disclosure. Handles and rubberized grip surfaces do not modify the basic intent of the invention, but are known to persons having ordinary skill in the art as details that amplify the utility of the invention. Likewise, in FIG. 15, the tube member 17 d is modified with a handle 87 the does not diminish the scope of the disclosure, rather, such variants are included within this disclosure by this reference. In a like manner, nothing within this disclosure limits it to practice in the context of stainless steel embodiments. Any suitable material such as polymeric plastics and alternate metals are also encompassed with the practice of the invention.

Just as the system 20 as portrayed in FIG. 14 is defined by the inclusion of two male engagements on the tube member 17 c, the system 20 can be practiced with equal facility as is defined by a tube member having female engagements on opposed ends (and on the open end of the Dewar flask (not shown)) as in FIG. 15. Also just as the system 20 depicted in FIG. 13 is defined by the male threading on the tube member 17 c, in the system 20 of FIG. 14, joining members, including the lid 32 b, the connector 23 b, the septum 13 b, and the base 31 b must have male engagement surfaces, as depicted, to suitably fulfill their roles in the modular system. The “gender” changer or ring member 17 g is a shortened tube member 17 f.

While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. For example, the container 10 could be made of stainless steel or other materials rather than a polymeric material; the insulated volumes could be evacuated rather than being air-filled, or alternatively foam filled; other attachment means such as cam lock latches could be used to removably attach the septum 13 to the tube member 17 rather than using two cooperative series of threads 56, 58; other attachment means could also be used to removably attach the tube member 17 to the septum 13 or connector 23 rather than using two cooperative series of threads; the exterior of the system 10 could be a different shape; and different gripping means such as handles or raised knobs could be used as gripping surfaces on the tube member 17. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
